Fluoride is a naturally occurring mineral that protects against cavities in children and adults and helps repair the early stages of tooth decay. Fluoride makes tooth enamel more resistant to the acid attacks that lead to cavities.
Exposure to fluoride can help to prevent tooth decay and improve oral health. Regular use of fluoride toothpaste is the best way to ensure a good preventive effect.
Fluoride is safe and effective if applied at recommended levels. Fluoride inhibits bacterial acid production on the tooth, stops enamel demineralization, and enhances enamel repair.
Fluoride can be added to water, salt or milk as part of community interventions; it can be professionally applied or prescribed as a gel, varnish or tablets, and it is an essential component of oral health self-care in toothpaste and mouthwash.
